lb. Ptillmnium Tex^num C. & E. Plants 7-12 dm. tall: leaf -segments numer- 

 ous and rather densely clustered: umbel-rays numerous, over 2.5 cm. long at maturity: 

 bracts lobed: fruits oval, about 2 mm. long, obtuse. — Differs from P. capillaceum in 

 oval fruits, the large petals and the discoid stylopodium. 



In low grounds and swamps, eastern Texas. Fall. 



Page 872, after Foeniculum Foeniculum, insert: 



31a. ANETHUM L. 



Annual or biennial herbs, resembling Foeniculum. Leaves alternate: blades 

 decompound, the segments narrowly linear or linear-filiform. Flowers in naked 

 compound umbels. Hypanthium truncate. Petals yellow. Stylopodium depressed. 

 Styles short. Fruit slightly elongated, flattened dorsally: carpels ribbed and with 

 narrow lateral wings. — Differs from Foeniculum in the dorsally flattened fruits and 

 the depressed stylopodium. 



1. Anethum grav^olens L. Plants 1 m. tall or less, glaucous: leaf-segments 

 numerous: umbels many-flowered, the rays unequal: sepals minute: petals ovate to 

 orbicular, 1 mm. long or less: fruits oblong to oval-oblong, 4.5-5 mm. long, glaucous. 



In waste places and fields, Connecticut to Illinois, California, Florida and Arkansas. 

 Naturalized from the Orient. Dill. 



Page 873, after Angelica villosa, insert: 



la. Angelica atropurpurea L. Plant 11-21 dm. tall, the stem dark-purple: 

 leaflets 2.5-7.5 cm. long; blades thick, ovate to lanceolate, coarsely serrate: umbel- 

 rays 2.5-7.5 cm. long: pedicels 10-16 mm. long: corolla white or greenish-white: 

 fruits oblong, 6-6.5 mm. long, glabrous. — Differs from A. Curtisii in the fruits which 

 have numerous oil-tubes and narrow wings. 



In moist thickets and swamps, Labrador to Minnesota, Delaware and Arkansas. 

 Spring and summer. Great Angelica. 



Page 880, after Monotropsis odorata, insert : 



la. Monotropsis L^hmanae Burnham. Stems 4-10 cm. tall, mainly brownish- 

 purple: flowers not fragrant: calyx about twice as long as the corolla: sepals 7-8 

 mm. long: corolla mainly pink, the lobes about as long as the tube. — Differs from 

 M. odorata in the odorless flowers, the relatively long calyx and the long corolla-lobes. 



In thickets, western North Carolina. Fall. 



Page 883, after Asalea lutea, insert: 



la. Azalea austrina Small. A shrub mostly 3 m. tall or less with irregular 

 branches and softly pubescent and usually glandular twigs. Leaf-blades oval, obovate, 

 oblong or oblong-spatulate, 2.5-9 cm. long, acute or abruptly gland-tipped, rather 

 firm in age, finely pubescent, usually permanently so, ciliate, short-petioled: flower- 

 clusters expanding before the leaves; pedicels glandular-pubescent: calyx-lobes del- 

 toid to triangular-lanceolate, acute, glandular-ciliate: corolla yellow or orange, 2-3 

 cm. long, the tube scarcely dilated up to the limb, finely glandular-pubescent, the 

 lobes broad, acute or abruptly short acuminate: anthers 2. .5-3 mm. long: capsules 

 rather slender, slightly narrowed upward, 2-2.5 cm. long, finely glandular-pubescent. — 

 Differs from A. lutea in the softly pubescent twigs, the roughish-pubescent reticu- 

 late leaf -blades, the very short calyx-lobes, the smaller corolla and the slender glandu- 

 lar-pubescent capsules. 



In woods and on banks of streams, Chattahoochee region, middle Florida. Spring. 



Page 883, after Azalea arborescens, add: 



9. Azalea prunlfolia Small. A shrub 3 m. tall or less with irregular branches 

 and glabrous twigs. Leaf-blades obovate, oval or narrowly elliptic, 2.5-8 cm. long, 

 abruptly gland-tipped, acute or slightly acuminate, deep-green above, pale-green be- 

 neath, glabrous, except for scattered hairs on the midrib and on the veins beneath, 

 and the ciliate margins, slender-petioled : flower-clusters expanding after the leaves: 

 pedicels hirsute: calyx-lobes ovate, coarsely long-ciliate, obtuse: corolla white or pink, 

 2-2.5 cm. long, the tube glabrous or with scattered hairs, gradually dilated from the 

 base to the limb, the lobes broad, abruptly pointed: anthers 2.5-3 mm. long: cap- 

 sules gradually narrowed upward, about 2 cm. long, strigose. — Differs from A. arbores-
